I've picked up St. Dalfour fig jam from Aux Délices in the Byward Market. I'm pretty sure that St. Dalfour jams are available at other stores in the Market, too, but I can't recall specifically which ones.
and if more than just fig interests you, bOdhi...Sultan's (on Bank, just south of South Keys) has an especially good fig/orange spread (99% fruit). SMS brand.
